The logging characteristics and evaluation methods of hydrocarbon source rock in coal measures

摘要

Hydrocarbon source rock is the foundation of oil and gas exploration research. At present, geochemical methods are still the mainly used for hydrocarbon source rock studies, which is hard to obtain a continuous data on a single well owing to the limited samples and experimental fees. Logging information has a high vertical resolution and continuous data, and the use of logging characteristics of hydrocarbon source rocks in coal measures provides a new approach in the correct evaluation for hydrocarbon source rocks. Quantitative evaluation and qualitative identification methods of hydrocarbon source rocks in coal measures were introduced, such as cross plot method, AlogR method. The data of TOC by using the methods above is calculated which provides reference for comprehensive evaluation of hydrocarbon source rocks.
